“People are ruder today because they are rushed and more ‘time poor’ than ever before, ” says Patsy Rowe, “ Manners have fallen off the radar(雷达). ” Due to our strong attraction to electronic equipment it is a wonder more people don’t wake up each morning and greet the singing birds with a complaint（抱怨）about the noise. Here are some examples of rudeness.
Some people prefer to do almost everything over the internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don, t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous（匿名的） rude messages by email.
However, rudeness is never acceptable, Don, t assume it is OK to be rude if the person you, re in touch with won, t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.
We shouldn′t blame technology for our shortcomings. Technology is here to help us, but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more help if we′d publicly acknowledge good manners when we see them.What can be inferred from the underlined sentence in Paragraph I?
| A．People can tell good from bad behavior. |
| B．Radar is able to observe human behavior. |
| C．People care little about their behavior. |
| D．Radar can be used to predict human behavior. |
Some people are less willing to deal with humans because

| B．they are growing too independent |
| C．they have to handle many important messages |
| D．they have to follow an evolutionary step backward. |
The author thinks sending unsigned awful messages is
| A．Ridiculous | B．disgusting | C．acceptable | D．reasonable |
What can we learn from the last paragraph?
| A．We should applaud good behabior. |
| B．Technology can neber be blamed |
| C．We should keep pointing out mistakes. |
| D．Technology will take over lives one day. |

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机)only when it is full 。Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.Which of the following is most likely to lead to less groundwater?
| A．Using river water. | B．Throwing batteries away. |

Multitasking
People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted (分心) and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.” The research led by Sanbonmatsu indicates that people who multitask.
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．are more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |
When Sanbonmatsu and his colleagues conducted their research, they .
| A．assessed the multitasking ability of the students |
| B．evaluated the academic achievements of the students |
| C．analyzed the effects of the participants’ tricky mental tasks |
| D．measured the changes of the students’ understanding ability |
According to Sanbonmatsu, people multitask because of their _.
| A．limited power in calculation | B．interests in doing things differently |
| C．inability to concentrate on one task | D．impulsive desire to try new things |
From the last paragraph, we can learn that multitaskers usually____ .
| A．drive very skillfully |
| B．go in for different tasks |
| C．fail to react quickly to potential dangers |
| D．refuse to explain the reasons for their behavior |
